SEMICONVERTIBLE CAR.

To all whom it 'may concern:

Be it known that I, PETER M. KLING, a

citizen ol the United States of America, re

siding in the city of Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inSeniiconvertible Cars, for which the following is a specification.

My present invention relates to semiconvertible car construction and hasfor its ob- `ject to so construct the window posts of a car that toomuch lateral space between the panels and lining or too much top spacein the car will not be taken up by the upper sash section.

Heretofore it has been proposed to have two superposed sashes for a carwindow. It has also been proposed to have both of said sashes droppedinto suitable pockets between the panels and lining. I/Vhere it isdesired to equip the car with cross seats, this has inf volved too muchlateral space. It has also been proposed to have both sashes movedupwardly into the top of the car. rThis involved too much head spacewhere the height of the car was necessarily limited. It

has also been proposed to have the upperv sash moved upwardly toretracted position and the lower sash moved downwardly to retractedposition. The method in which this has been done heretofore has involvedeither a special construction of car frame, impairing the interiorappearance of the car, or it has involved too much top space interferingwith tall people.

My present invention relates to that class of semiconvertible carconstruction for which Letters Patent Number 693,611, were issuedFebruary 18, 1902 in which one sash, the upper one, is moved upwardly toretracted position and the other, the lower one, is moved downwardly toretracted position. In a semiconvertible car construction made inaccordance with the present invention an extremely small proportionateamount of head space and lateral space is utilized and the interiorappearance of the car is improved. My construction is adapted to anywell known construction of car frame and does not necessitate a specialconstruction of the car frame provided therewith.

My invention is clearly described in the following speciiicationandillustrated in the accompanying drawings, in which like referencecharacters refer to like parts and in which Specification of LettersPatent.

Application led October 2. 1905. Serial No. 280,912.

Patented March 3,1908.

Figure 1 is a vertical section of one side of a semiconvertible car bodyshowing the windows closed. Fig. 2 is a similar view on a larger scale.Fig. 3 is a vertical section of the other side of a semiconvertible carbody showing the windows open.

1 is the roof of the car, 2 the head lining, contiguous to the roof, 3the Jfiller, 4 the upper board or plate of a vertical side car-body, 5the curtain roller pocket, 6 the curtain runner, 7 the lower sash whichis rectangular and straight, S the upper sash section which is curved inform carrying the pane 9 which is `between the head lining 2 and roof 1.11 is a car post in which the pocket l0 is located.

By forming the upper sash section 8 in form of a curve less room is usedin forming the pocket into which the sash section 8 is pushed when thewindow is opened, since the sash section may be shifted from thevertical plane -it occupies when projected or lowered to the diagonalplane it occupies when retracted or raised without materially decreasingthe head space in the upper corner of the side of the car.

It will be noted that a curved pocket conforms more nearly to the cornerof the side of a car of substantially rectangular construction thanwould a straight pocket which in order to receive its sash section mustbe disposed diagonally across the corner of the side of the car. Byconstructing the upper sash. section and its pocket in the form of acurve greater ease of operation is produced over that form of straightsash section and pocket where the sash section is abruptly changed. fromone plane to another in its retraction, such for instance as where theuppersash section is swung on a pivot traveling in the guideways andthrown across the corner of the side of the car. Since I have provided asatisfactorily working upper sash section I am enabled to employ astraight lower sash 7 which is dropped into the usual pocket 12 betweenthe panel and lining of the car. As the lower sash panel is straight andthe up er sash pocket terminates at its lower end a acent to the upperend of the lower sash panel and is held toward it in a curve, the curvedupper sash section when down as shown in Figs. l and 2 is forced by thecurve of the sides of its guiding pocket against the upper rail of thelower sash, thus holding it from vibration.

This improvement is especially advantageous in the construction of carsdesigned for use in subways and tunnels, wherein the height of the caris necessarily limited and wherein overhead ventilation is necessary andit is desirous to make the lower sash 7 immovable.

While I have stated in the specification that the lower sash 7 isdropped into a suitable pocket l do not wish to be limited to such anarrangement since it may be desirable to make lower sash 7 rigid toprevent passengers from thrusting their heads or limbs out of thewindows.

Having thus described my invention the following is what I claim as newtherein and desire to secure by Letters Patent:

1. A semiconvertible car comprising a vertical side body, a roof, a headlining contiguous to the roof, an up er board and a post formed with. asingle slightly curved pocket for the upper sash section constructedwith parallel sides, and extending a short distance beyond the loweredges of the rooi` and the head lining, and approximately tangential tosaid vertical side body, and with a lower pocket, a short curved sashsection shiftable in said curved pocket and a lower sash, in said lowerpocket, against the u per rail of which the curved sash section isforced to hold the lower sash from vibration.

2. A semiconvertible car comprising a vertical side body, a roof, a headlining contiguous to the roof, an up )er board and a post formed with asingle slightly curved pocket for the upper Isash section constructedAwith parallel sides, and extending a short distance beyond the loweredges of the roof and the head lining, and approximately tangential tosaid vertical side body, and a short curved sash section having a flatpane set therein as a chord to the curve of the curved sash seetion, andshiftable in said curved pocket.
